    Compiles and runs on:
- Red Hat Enterprise Linux ES release 4 (Nahant)
 * libipvs from ipvsadm-1.24  
         2 files are needed from libipvs:
         /usr/include/ipvs/libipvs.h 
         /usr/lib/libipvs.a
 * kernel 2.6.14.1  (/usr/src/linux/include/net/ip_vs.h is needed)
 * net-snmp-5.1.2-11.i386.rpm
 * net-snmp-devel-5.1.2-11.i386.rpm
 * net-snmp-libs-5.1.2-11.i386.rpm 
 * lm_sensors-devel-2.8.7-2.i386.rpm


- Fedora Core release 3 (Heidelberg)
net-snmp-5.1.2-11.i386.rpm
net-snmp-devel-5.1.2-11.i386.rpm


The installation process that worked for me (mainly these are instructions from original README
in the package, but here paths and snmpwalk arguments are different):

1. Compile libipvs:
	download ipvsadm-1.24.tar.gz
	tar zxvf ipvsadm-1.24.tar.gz && cd ipvsadm-1.24/libipvs
	make
	cp libipvs.h /usr/include/ipvs
	cp libipvs.a /usr/lib

2. Compile ucd-snmp-lvs-module-0.0.2a
	make && make install
3. Add following line to /etc/snmp/snmpd.conf
	dlmod lvs /usr/local/share/snmp/dlmodules/lvs.so 
4. Copy mibs:
	cp OC-MIB.txt LVS-MIB.txt  /usr/share/snmp/mibs/
5. Add following line to /etc/snmp/snmp.conf
	mibs +OC-MIB:LVS-MIB

6. Insmod ip_vs and (optionally) create some VIP definition
7. Run snmpd:
	/usr/sbin/snmpd  -f -V -L -Dlvs 
8. Run snmpwalk:
	snmpwalk -Os -c public -v 2c localhost enterprises.opencon.lvs	

NOTE: if you have fresh snmpd.conf then probably you will see snmpwalk output:
lvs = No more variables left in this MIB View (It is past the end of the MIB tree)

You can add following lines to snmpd.conf ('+' marks which line was added).
This is an example and you should be very careful in granting access to your snmp
coz potentially it can be a security issue:

+view all    included  .1
view    systemview    included   .1.3.6.1.2.1.1

+access  notConfigGroup ""      any       noauth    exact  all none none
access  notConfigGroup ""      any       noauth    exact  systemview none none


8a. Restart snmpd and run snmpwalk again.
